About the tides at Massaponax
Massaponax has a semidiurnal tide: two highs and two lows of similar height each day, about 12 hours and 25 minutes apart. The pattern follows the reference station at Washington, Potomac River. The average range is about 2.1 ft. Spring tides add a little more at both ends. The next spring tides peak on October 27, with a range of 2.9 ft. Neap tides follow today, when the range shrinks to 1.5 ft. In the next 12 months the highest predicted tide here is 3.2 ft on September 30, and the lowest is −1.0 ft on January 24.
Massaponax is a subordinate station. NOAA predicts its tides by adjusting Washington, Potomac River: highs come about 39 min and lows about 41 min earlier than there. The nearest other station is Park Turn, 9 mi away, where high tide comes about 1 h 16 m earlier.
Predictions are based on Washington, Potomac River.
